Invaders
The Invaders was a team of super-powered champions who fought on behalf of the Allied powers during World War II. The founding members agreed to band together to act as special agents of the Allied forces, often taking direct orders from Allied officials. Typically, the Invaders would discover or were asked to fight costumed criminals who worked for the Axis nations, such as the Red Skull, Master Man, U-Man, Agent Axis, and others. The Invaders' subsequent adventures in the European front led them to adopt Big Ben as their unofficial headquarters. When the war was over, the many members of the Invaders were asked to stay together as the All-Winners Squad, though over the years their members would either depart to pursue their own lives, retire, or become incapacitated.
